N-Acetylcysteine (NAC) is a precursor to glutathione synthesis and also acts on its own to reduce the effects of reactive oxygen species. NAC also has mycolytic properties and decreases viscosity of lung secretions. NAC has been shown by studies to have a protective effect on the liver and has been used to manage acetaminophen overdose, due to its ability to enhance hepatic and mitochondrial levels of glutathione and by supporting the mitochondrial energy metabolism.


  • Expected to reduce the severity of symptoms of influenza, HIV and avian flu
  • Can be used to support glutathione synthesis thereby increasing the body’s total antioxidant capacity
  • Has mucolytic properties and can reduce the viscosity of lung secretions and can be used to reduce symptoms in patients with COPD
  • Has a protective capacity for the liver and is used to treat acute acetaminophen poisoning
  • Can be used to treat diabetic neuropathy and encephalopathy through its ability to reduce oxidative stress and apoptosis
  • Can be used to treat symptoms associated with osteoarthritis as it has the ability to reduce inflammation in synovial fluids
  • May reduce the smooth muscle cell proliferation that occurs after venous graft surgery, therefore preventing vessel stenosis
  • Can be used to treat diseases associated with fibrosis as it
